PERMANENT WAY FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent. No. 279,280, dated June12, 1883.

' Application iled September 22, 1882. (No model.)

To a/ZZ whom it may concern: o

Be it known that I, FRIDOLF SCHAUMAN, of Landskrona, in the Kingdom ofSweden, but at present residing at 30 Finsbury Pavement, London, E. C.England, have invented certain new and useful Improvements in PermanentWays for Railways, of which the following is a specification.

The object of this invention is to obtain a durable, elastic, and safepermanent way for railways 5 and the invention consists of sleepers madeof stone or concrete, and provided with washer-plates, which are lcomposed or prepared cork, and interposed as an elastic medium betweenthe rails and the sleepers, the cork washer-plates being bolted insuitable manner to the sleepers.

In the accompanying drawings, Figures l and 2 represent a verticaltransverse section and a plan of my improved permanent way forrailroads. Figs. 3 and 4 are a vertical transverse section and a plan ofa modified construction of the same. Figs. 5 and are plans, showingdifferent forms of sleepers, and Fig. 7 is a vertical transverse sectionof the perlnanent way shown in Fig. 6.

Similar letters of reference indicate correspending parts.

The stone or concrete sleepers c are laid in the ballast of the road,and are each furnished with four bored or cast.boltholes, throughwhichpass wrought-ironbolts c c, having heads at their lower ends andnuts e at their threaded upper ends. rIhe compressed or prepared corkwasher-plates b are placed at or near the edges of the stone or concretesleepers a, and so that the aforesaid bolts c pass also through holesformed in them corresponding to the holes in the said sleepers. The baseof the rails f are placed directly on the compressed or prepared corkwasher-plates b and secured thereto and to the sleepers by'springclipplates d, of suitable form and dimensions, as shown in Figs. l and2. The spring clipplates d bear on the base of the rail, while theirother ends bear on the compressed or prepared cork plates b. Ihe bolts cpass through holes in the spring clip-plates d, the nuts e bearing uponthe said spring clip-plates so as to hold the rails f, the corkwasher-plates b, and the stone or concrete sleepers a jointly together.

In case reversible rails are used, they are secured by wedges intochairs d', which are placed on the cork washenplates, the chairs,washer-plate, and sleeper being connected by bolts and nuts, as shown inFigs. 3 and 4.

. The desired width between the rails is secured by transverse irontie-rods. By reducing or increasing the thickness of the compressed orprepared cork washer plates b, the road can readily be adjusted.

Having thus described my invention,I claim as new and desire to secureby Letters Patent- An improvement in permanent ways for railroads,consisting of stone or concrete sleepers a, provided with bolt-holes, incombination with compressedcork washer-plates b, rails f, springclip-plates d, bolts c, and nuts e, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses. l
